Design firm PostlerFerguson has created Olympus, a 1:1 model of one of Concorde's engines, which will be on display in the window of Selfridges until October 22.

The model is both a eulogy to the design feat of Concorde but also to Selfridge's own heritage - when the store first opened in 1909 it displayed the Bleriot XI, the first airplane to cross the English Channel from Dover to Calais.

Pleasingly, despite the technical brilliance it is celebrating, the model was created by PostlerFerguson by using a maintenance manual purchased on eBay for £6 and lots of styrofoam, paper and glue.
